Okay, this may be a strange question, but does anyone have an opnion about using pecan shells in a run? I have several large bags of the shells that I hate to just throw away. However, I don't think they'd absorb any moisture, and they may really have too many sharp edges... and I may have just answered my own question. Well, to modify it, then- does anyone have any suggestions of something useful to do with all these pecan shells?? Thanks in advance!
